SQUIRE TONEY, OF VIROQUA, WISCONSIN, ASSIGNOR OF ONE-HALF TO MARY BROWN, OF SAME PLACE.

LATH.

SPECIFICATION forming part of Letters Patent No. 487,166, dated November 29, 1892. Application filed June 18,1892. Serial No. 437,120. (No model.)

To all whom it may concern:

Be it known that I, SQUIRE TONEY, a citizen of the United States of America, residing at Viroqua, in the county of Vernon and State of Wisconsin, have invented certain new and useful Improvements in Laths; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object to provide a simple, cheap, and effective lath or sheathing, one side of which is channeled or grooved, While the other side is made concave, so that when applied to the studding it will be bent to converge the side walls of the channels which will retain the plaster when placed thereon.

In the accompanying drawings, forming part of this specification, Figure l is a perspective sectional view showing a lath made in accordance with my invention. Fig. 2 is a sectional view showing the lath applied.

A designates the lath or strip, which is of suitable width, one edge of the same being cut at right angles, while the opposite edge is cut away to provide a concave recess a,adjacent to which the straightedge of the abutting strip will lie. The surface of the lath against which the plaster is placed is provided with rectangular channels or grooves 19 b and the back of the lath is concave from edge to edge. By making the back of the lath concave when it is nailed against the studding or supporting-strips the central part will be bent to bring the rear surface on a straight line, thus drawing the upper edges of the channels or grooves 19 b, so that dovetailed channels or recesses will be provided, which will hold the plaster securelyin place. The concave edge of one lath in connection with the adjacent one also forms a key.

A lath thus constructed can be cheaply made, as the channels or grooves b b can be cut in by an ordinary matching-machinesuch as is used in all lumber-mills-atasingle operation, and there are no projecting parts or overlapping edges which are liable to be broken in transportation. Asthe lath passes through the cutting-machine but a single time, a much cheapergrade of lumber can be used. By hollowing out the back of the lath I not only form dovetailed keys when applied, but avoid the objection so common to other sheathing-laths-to wit, that of cracking the mortar by bulging or swelling.

I claim 1. A wooden lath or sheathingof less thickness at its center than at its edges and provided with a straight surface on one side, the straight surface having channels or recesses formed therein, substantially as set forth.

2. As an improved article of manufacture, a plastering strip or lath having a concave back, a concave edge, a straight edge, and intermediate rectangular channels or recesses b, substantially as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SQUIRE TONEY.
